How can I get na internship at Google, Apple, or Amazon?

Depends on what we're talking here, on a couple dimensions:

If you mean internships for this summer, it may be difficult to swing at large companies because they'll have already finished their hiring for summer 2017 internships. If you mean fall 2017 or later (e.g. summer 2018), then apply like in the fall or w/e, whenever it opens up.

For Google specifically, see https://careers.google.com/students/ - Amazon, Apple (also consider Facebook, Microsoft, etc) certainly have similar resources for student internships.

It would also help to know more about what you want specifically - aiming for a software internship? If so that's doable at big tech companies. Sales or business internships are also possible. Theoretical linguistics internship may be harder to swing... Google does have some computational linguists on staff, but it's very much like a PhD research thing, may be less geared towards hosting undergraduate internships (unless you are in a linguistics PhD program, then maybe that is a thing, idk).

For tech internships specifically, they'll be looking for people who can write a good amount of code, geared towards students in a computer science degree track with at least a few programming classes taken. For freshmen/sophomore with less experience there's an Engineering Practicum internship program, but it still assumes some reasonable coding ability.

There will be some positions at Google that use linguistics for software engineering, e.g. on translation or keyboard teams, but it won't be many. Hard to say if it'd be feasible to get matched to such a team, I'm not sure.

All of these companies are cutting edge and it's a great thing to steer your curriculum early on trying to get a job there!

My personal experience with Google is that what they say about it seems to hold true - getting an internship at Google is harder than getting into Harvard! However - with the right training and your language skills those things def can give you an edge!

Amazon is also extremely difficult as well bc it is also changing the world. But you seem to be on track with your language experience and focusing on specific training to streamline your goals.

I do know many people who work for Apple and that probably is a tad (very very slightly) less competitive but all three are extremely competitive. I do believe all 3 offer internships during the summer between junior and senior year of college.

Having said that they are all difficult - if you know what you are interested in - then certainly languages/ sign language is a significant asset as these are global companies and always looking for diverse skills.

There is a lot online about all of these companies and the programs they offer. You will find the internet is a great resource to find what they are specifically looking for in their job candidates.

Your picks are fantastic - you know where the smarts of the IT industry reside.

As Sylvia mentioned, you picked companies that are challenging to get internships with. However, I don't see any harm to reach out to their human resource department to see where these companies host college fairs.

I know folks at Verizon that make field trips to certain schools, so the folks at those schools could have a better opportunity than others at an internship.

Also - don't give up hope! If you can't work in IT with one of those companies, you could possibly work in a non-IT sector. I know Amazon does seasonal hiring, and if you get lucky and exercise some STRONG networking, maybe you can create an advantage for yourself.

Reach for those superstar companies, but don't totally dismiss a 'plan b' company if you need to.
